IMPROVEMENT IN HORSE HAV-RAKES.

Specification forming part of Letters Patent No. 119,320, dated September 26, 1871 antedated September 11, 1871.

To all 'whom it may concer/n:

Be it known that I, ARcHrnLD L. CHUBB, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Sulky Horse-Rakes; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this speciiication, in which- Figure 1 shows my invention in perspective. Fig. 2 shows an enlarged view of my device for securing the teeth to the axle-beam. Fig. 3 is a plan view of the plate by means of which the upper ends of the teeth are secured to the front side of the axle-beam.

The nature of this invention relates to certain improvements in the construction of sulky horserakes; and consists in the peculiar manner in which the spring-teeth are secured to the aXlet beam, sol that they may have a certain amount rear ends of the shafts to eachother, are secured the clearing-teeth h, which project rearward from said girt under the axle-beam. F is a sev ries of curved teeth, projecting to the rear of said beam and downward in the form shown, and they are secured to the said beam as follows:

i It will be noticed that these teeth are round, and

it is desired that they may beso attached to the beam that they may have a certain vertical motion, while, at the same time, they may be prevented from rolling or turning. To accomplish this end I secure a plate, Gr, to the beam by means of screws i or any other suitable device, so that said plate will be held rigidly in position. This plate is provided with a slot, g, terminating in a hole, h, through which one 4of the -bolts or screws 1 i t' is inserted to secure the plate to the beam. This slot is considerably narrower than the diameter .turn or roll inthe plate.

Atooth itis flattened or notched until the attened or squared part will freely enter the slot, the head of the tooth being inserted in the hole h and passed through the same until the flattened part will pass into the slot g. After the tooth is inserted the plate may be secured to the beam, as hereinbefore described, and the tooth will have a vertical movement without any tendency to p H is a series of guides, by means of which the teeth are held in their relative positions in their vertical movements. I is a seat for the driver, secured toV proper risers 7c, the lower ends of which are fastened to the forward shaft-girt J, and thence, passing upward and rearward, rest upon the cross-tie K, which forms also a foot-rest for the driver. L is a rod or stake, the lower end of which is rigidly secured to the axle-beam A; and m is a hook, or its equiv: alent, secured to the side of the seat, and it is designed, by its engagement with the rod or ,stake L, to retain the beam and teeth in position.

After the spring-teeth have gathered the hay,

and it is desired to deposit in awindrow, the operator dise'ngages the rod L from the hook m, when the weight of the driver, assisted by a push of the rod Lfrontward, tilts the axle-beam in the same direction, thereby raising the rake-teeth. As the clearing-teeth, which arerigidly secured y to the rear girt of the shafts, as hereinbefore described, project rearward, the rake-teeth, rising between them, are cleared of the hay. The driver then draws back the rod and re-en gages it with the hook, and repeats the operation as often as the rake-teeth become loaded. Theobject of allowing the vertical motion of the rake-teeth is to assist them in conforming to the inequalities of the ground.

Instead of the plate with slot, as described, for preventing the tooth from turning therein, two plates might be employed, each made in the form of an L, the lower parts turned toward each other, thereby forming a slot between the vertical parts. I consider my plate preferable to this, or to any known equivalent therefor, by means of which the notched or iiattened part of the tooth may be grasped and held in position; or a rectangular opening may be made in a plate of any form large enough to allow the head of the tooth to pass through, and after the notched or attened` part of the tooth has entered the opening it may be partially closed by means of another plate or 2. The guides H, in combination with the plate cover, which may be secured to the axlebeam by G, axle-beam A, and spring-teeth F, all constructscrews or bolts through both plates. ed, arranged, and operated substantially as de- What I claim as my invention, and desire to scribed and shown, for the purposes set forth. secure by Letters Patent, is- ARCHIBALD L. CHU'BB.
